Definitions
- the present disclosure reveals a new design for a linear actuator that modifies the positioning in adjustable furniture
- a linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor.
- Linear actuators are widely used within the area of adjustable furniture, such as beds, chairs, or tables, where they may be used for adjusting the position of adjustable furniture, such as the lifting and reclining of motion chairs, the height of a table, or the position of the mattress surface of a bed.
- the actuator is typically comprised of an electric motor drive assembly that drives a threaded spindle.
- the spindle is retained within a rigid arm, and the electric motor drive assembly is attached to the rigid arm with a plurality of threaded fasteners.
- a pusher block is threaded onto the spindle and is secured in linear recesses within the arm. As the electric motor drive assembly turns the spindle, the pusher block moves from one end of the arm to the other end. The direction of movement is determined by the direction of the spindle's rotation.
- One end of the prior art actuators may be secured to the adjustable furniture by a rear mounting bracket.
- the actuators are also attached to the furniture by a pair of levers or linkages.
- One end of the respective linkages is secured to the pusher block with a plurality of threaded fasteners.
- the other end of the respective linkages communicates with the furniture. Movement of the pusher block moves the linkages and adjusts the position of the furniture.
- the prior art linear actuators are costly to manufacture. Connection of the electric motor drive assembly to the rigid arm using threaded fasteners is disadvantageous because it is a time-consuming and complicated method of assembling the actuators.
- the prior art actuators are also difficult to mount on adjustable furniture. Use of threaded fasteners on the pusher block makes it difficult for assembly line workers to align the furniture so that the levers line up with threaded apertures in the pusher block.
- the present invention relates to an improved linear actuator.
- the improved linear actuator is designed to provide the moving force for adjustable furniture, such as beds, chairs, or tables.
- the improved linear actuator overcomes problems with the prior art by reducing the number of necessary parts and simplifying assembly to save production costs.
- the improved linear actuator is directed at use of the actuator in adjustable furniture
- the improved linear actuator may be adapted for use in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers, and in many other places where linear motion is required.

- FIG. 9 is an enlarged view of the dis-assembled rigid arm and holder of the linear actuator of FIG. 1 .
- FIG. 10 is an exploded assembly view of the linear actuator of FIG. 1 .
- FIGS. 1, 4, and 7 illustrate an embodiment of a linear actuator 16 according to the present disclosure.
- An electric drive motor assembly 2 is connected to a rigid arm 3 .
- the rigid arm 3 is formed of stainless steel or other suitable material, and also includes a plastic cover 17 .
- a threaded spindle 5 is retained inside the arm.
- a spindle nut 6 is threaded onto the spindle 5 , and a pusher block 7 is attached to the spindle nut 6 .
- the pusher block 7 straddles the rigid arm 3 and slides up and down the arm 3 as the electric drive motor assembly 2 turns the spindle 5 .
- a holder 4 is attached to the other end of the rigid arm 3 to retain one end of the spindle 5 and to provide mounting points for the actuator.
- the pusher block 7 provides a connection point for communicating force generated by the improved linear actuator 16 to the adjustable furniture.
- the top of the pusher block 7 incorporates a clevis 18 .
- Apertures in the clevis 18 are adapted to receive a clevis pin 19 or other suitable fastener.
- a single linkage 8 connects the pusher block 7 to a torque tube assembly 14 .
- An aperture at the lower end of the single linkage 8 is adapted to receive the clevis pin 19 .
- a cotter pin 20 may be used to secure the clevis pin 19 .
- Use of a clevis pin 19 to attach the linkage 8 and pusher block 7 eliminates the need for additional brackets and threaded fasteners to facilitate the attachment.
- the pin 19 also eliminates the need to mold threaded screw-receiving apertures into the pusher block 7 .
- FIG. 2 depicts an embodiment of the improved actuator 16 with the clevis 18 incorporated into the side of the pusher block 7 .
- a clevis pin 19 is used to secure the linkage 8 .
- FIG. 3 is a cross sectional view of this embodiment.
- FIG. 5 depicts an embodiment of the improved actuator 16 with the clevis 18 incorporated into the side of the pusher block 7 , with a threaded bolt 11 securing the linkage 8 .
- FIG. 6 is a cross sectional view of this embodiment.
- FIG. 4 is a side view of the improved actuator 16 .
- the single linkage 8 has a unique lever shape that may be adapted to fit specific requirements for different embodiments of adjustable furniture.
- a single dual angle bracket 13 is moveably attached to the upper end of the linkage 8 and may be attached to a torque tube assembly 14 that transmits the force of the actuator 16 to the adjustable furniture.
- FIG. 7 is a rear view of the improved linear actuator 16 .
- a bolt 12 (see FIG. 7 ) or similar fastener moveably secures the upper end of the single linkage 8 to the dual angle bracket 13 .
- Threaded fasteners 15 secure the dual angle bracket to the torque tube assembly 14 .
- the torque tube assembly 14 communicates with the adjustable furniture (not shown).
- a clevis pin 19 secures the lower end of the linkage 8 to the clevis 18 at the top of the pusher block 7 .
- a cotter pin 20 secures the clevis pin 19 .
- the improved linear actuator 16 simplifies the process of attaching the actuator 16 to the furniture because the clevis 18 makes it easier for assembly workers to align the furniture, torque tube assembly 14 , linkage 8 , and pusher block 7 . Additionally, assembly can be simplified through use of a single linkage 8 .
- FIG. 8 is a close up view of a disassembled electric drive motor assembly 2 and rigid arm 3 .
- the end of the rigid arm 3 contains one or more slots 21 .
- the slots 21 are adapted to receive one or more prongs 22 molded into the base of the drive motor assembly 2 .
- the slots 21 and prongs 22 allow the drive motor assembly 2 to be pressed onto the rigid arm 3 when the improved linear actuator 16 is assembled.
- the prongs 22 apply pressure to the arm 3 to securely hold the drive assembly 2 and rigid arm 3 together.
- Use of the slots 21 and prongs 22 eliminates the use of threaded fasteners to secure the drive assembly 2 and arm 3 together, decreasing manufacturing time.
- FIG. 9 is a close up view of a disassembled rigid arm 3 and holder 4 .
- the rigid arm 3 incorporates one or more fastener receiving channels 23 .
- One or more fasteners 24 pass through one or more apertures 25 in the holder 4 .
- threaded screws are used as fasteners 24 , but other appropriate fasteners may be used.
- the holder 4 is positioned next to the rigid arm 3 so the apertures 25 in the holder 4 align with the fastener receiving channels 23 in the arm 3 .
- the fasteners 24 are then installed, securing the holder 4 to the rigid arm 3 .
- the use of one or more threaded screws to secure the holder 4 to the arm 3 simplifies assembly of the improved linear actuator 16 and leads to faster production.
- FIG. 10 is a perspective view of the disassembled improved linear actuator 16 with the pusher block 7 already positioned on the spindle 5 .
- the electric drive motor assembly 2 is comprised of an electric motor 26 , lower assembly cover 27 , and upper assembly cover 28 .
- One or more threaded screws 29 secure the electric motor 26 to the lower assembly cover 27 and a series of threaded screws 30 secures the upper assembly cover 28 to the lower assembly cover 27 .
- a worm gear (not shown) is attached to the output shaft 31 of the electric motor 26 .
- the worm gear turns a worm wheel 32 attached to the end of the threaded spindle 5 .
- One end of the worm wheel 32 rests in a worm wheel bearing 33 to facilitate rotation of the spindle 5 .
- the spindle 5 rests within the rigid arm 3 .
- a plastic cover 17 shields the spindle 5 .
- the spindle nut 6 is threaded onto the spindle 5 and is attached to the pusher block 7 .
- Switches 34 are mounted within the rigid arm 3 using threaded screws 35 . The switches 34 sense the position of the pusher block 7 and are connected to the controls (not shown) and power source (not shown) for the improved linear actuator 16 . When the pusher block 7 contacts a switch 34 , power to the electric motor 26 is cut and travel of the pusher block 7 is stopped.
- the holder 4 is attached to the end of the rigid arm 3 using threaded fasteners 24 that are screwed into fastener receiving channels 23 in the rigid arm 3 .
- the holder 4 may incorporate apertures 36 for receiving fasteners 37 that can be used to attach the actuator 16 to mounting points on the frame of a piece of adjustable furniture.
